[0037] In the description of the present utility model, unless otherwise clearly defined, terms such as setting, installing, connecting, assembling, and matching should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model based on the specific content of the technical solution.

[0038] Reference Figures 1 to 6 As shown, the first embodiment of the utility model provides a compressor, which is applied to a refrigeration device, and the refrigeration device can be a refrigerator, an air conditioner or a water dispenser, etc. The compressor is used to compress the refrigerant and transport it to the refrigeration system of the refrigeration device, so that the refrigeration system can use the refrigerant to achieve heat exchange and refrigeration.

[0039] Reference Figure 1 As shown, it can be understood that the compressor includes a compressor housing 100, a bracket 200 and a liquid reservoir 300, wherein the compressor housing 100 is roughly a columnar structure arranged in the up-down direction, and a pump assembly is installed in the compressor housing 100, and the pump assembly is used to compress the gaseous refrigerant into a high-temperature and high-pressure refrigerant. The pump assembly is a conventional assembly in the field of compressor technology, and the specific structural composition of the pump assembly is not further described here. It is easy to understand that during the operation of the pump assembly, the high-speed rotation of the rollers in the pump assembly will generate vibration.

[0040] Reference Figure 1As shown, it can be understood that the compressor housing 100 includes a first main housing 110 and a first upper housing 120. Of course, the compressor housing 100 also includes a first lower housing 130. The first main housing 110 is a cylindrical structure. The first lower housing 130 is installed at the lower end of the first main housing 110 to close the lower end opening of the first main housing 110. The first upper housing 120 is installed at the upper end of the first main housing 110 to close the upper end opening of the first main housing 110. The first lower housing 130 and the first main housing 110, the first upper housing 120 and the first main housing 110 are all welded and fixed. The top of the first upper housing 120 is provided with an exhaust port 121 for discharging the refrigerant.

[0041] Reference Figure 1 As shown, it can be understood that the accumulator 300 is located radially outside the compressor housing 100, and the accumulator 300 includes a second main housing 310 and a partition 340. Of course, the accumulator 300 also includes a second upper housing 320 and a second lower housing 330. Similarly, the second main housing 310 is a cylindrical structure, and the second lower housing 330 is installed at the upper end of the second main housing 310 to close the lower end opening of the second main housing 310. The second upper housing 320 is installed at the upper end of the second main housing 310 to close the upper end opening of the second main housing 310. The second lower housing 330 and the second main housing 310, and the second upper housing 320 and the second main housing 310 are all welded and fixed. The top of the second upper housing 320 is provided with an air inlet 321 for introducing a refrigerant. The liquid reservoir 300 further includes an air intake pipe 350, which is mounted on the second lower housing 330, the lower end of which extends downward from the second lower housing 330 and is connected to the air intake end of the cylinder of the pump assembly, the upper end of which extends upward into the second main housing 310, and the upper end of which is slightly lower than the upper end surface of the second main housing 310. It is easy to understand that the number of the air intake pipes 350 is equal to the number of the cylinders of the pump assembly.

[0042] Reference Figure 1 and Figure 6 As shown, it can be understood that the partition 340 is installed in the second main shell 310. Specifically, the longitudinal section of the partition 340 is roughly U-shaped, and the longitudinal section is a section parallel to the up and down direction. The partition 340 is welded and fixed to the inner wall of the second main shell 310, or the partition 340 and the second main shell 310 are interference fit. The partition 340 is provided with a first through hole 341 and a plurality of second through holes 342, wherein the number of the first through holes 341 is equal to the number of the air inlet pipes 350, and the inner diameter of the first through hole 341 matches the outer diameter of the air inlet pipe 350, and the air inlet pipe 350 is correspondingly penetrated through the first through hole 341. Therefore, the partition 340 can provide a radial support force for the air inlet pipe 350 along the second main shell 310, prevent the air inlet pipe 350 from swinging in the radial direction, and improve the installation stability of the air inlet pipe 350.

[0043] Reference Figure 1 and Figure 6 As shown, it can be understood that the second through hole 342 penetrates the partition 340 in the up-down direction, so that the space above the partition 340 in the second main housing 310 is connected to the space below the partition 340, and the plurality of second through holes 342 are arranged at equal intervals along the circumference of the second main housing 310. Since the refrigerant entering the second main housing 310 from the air inlet 321 exists in two states, gaseous and liquid, in order to prevent the liquid refrigerant from entering the cylinder of the pump body assembly and causing liquid hammer, the partition 340 is provided, and the gaseous and liquid refrigerants flow to the partition 340, and the liquid refrigerant will adhere to the partition 340 and flow along the wall of the partition 340, and then flow to the bottom of the liquid reservoir 300 through the second through hole 342, while the gaseous refrigerant enters the air inlet pipe 350 and flows to the cylinder of the pump body assembly, so that the partition 340 can achieve gas-liquid separation and improve the reliability of the compressor.

[0044] Reference Figure 1 and Figure 3 As shown, it can be understood that the bracket 200 is located between the compressor housing 100 and the liquid reservoir 300. Specifically, one end of the bracket 200 is connected to the outer wall of the first main housing 110, and the other end is connected to the second main housing 310. The bracket 200 and the first main housing 110, and the bracket 200 and the second main housing 310 are all welded and fixed. Therefore, the bracket 200 connects the liquid reservoir 300 and the compressor housing 100 to each other, which is conducive to ensuring the installation stability of the liquid reservoir 300.

[0045] Reference Figure 1 As shown, it can be understood that along the height direction (i.e., the up-down direction) of the first main housing 110, the bracket 200 has an upper end surface and a lower end surface, the first main housing 110 has an upper end surface, and the upper end surface of the first main housing 110 is higher than the upper end surface of the bracket 200. It is defined that along the height direction of the first main housing 110, the minimum distance between the upper end surface of the bracket 200 and the upper end surface of the first main housing 110 is H1, which satisfies 10mm≤H1≤20mm, and at the same time, the partition 340 is located between the plane where the upper end surface of the bracket 200 is located and the plane where the lower end surface of the bracket 200 is located.

[0046] Reference Figure 1As shown, it can be understood that, in the second main shell 310, except for the connection with the second upper shell 320 and the connection with the second lower shell 330, the structural strength of the connection with the partition 340 is higher than that of other positions. To this end, the partition 340 is located between the plane where the upper end surface of the bracket 200 is located and the plane where the lower end surface is located, which can improve the connection strength between the bracket 200 and the second main shell 310, reduce the deformation of the second main shell 310, thereby enhancing the support of the bracket 200 to the second main shell 310, that is, enhancing the support of the bracket 200 to the liquid reservoir 300, thereby increasing the installation stability of the liquid reservoir 300, improving the natural frequency of the liquid reservoir 300, thereby reducing the high-frequency resonance between the liquid reservoir 300 and the pump body assembly, improving the stability of the compressor, and effectively reducing the high-frequency noise generated during the operation of the compressor.

[0047] Reference Figure 1 As shown, it can be understood that, since the lower end of the reservoir 300 is connected to the compressor housing 100 through the air intake pipe 350, a connection structure already exists between the lower end of the reservoir 300 and the compressor housing 100. The bracket 200 is mainly used to connect the upper structure of the reservoir 300 to the compressor housing 100. Therefore, the connection position of the bracket 200 on the first main housing 110 is made higher, and the bracket 200 is close to the upper end surface of the first main housing 110, that is, H1≤20mm, which can make the connection position of the bracket 200 on the reservoir 300 also higher, increase the distance between the two connection positions of the reservoir 300 and the compressor housing 100 in the height direction of the first main housing 110, thereby further increasing the installation stability of the reservoir 300, reducing the swing amplitude of the reservoir 300, thereby increasing the natural frequency of the reservoir 300, and reducing high-frequency noise.

[0048] Reference Figure 1 As shown, it can be understood that since the installation position of the partition 340 inside the liquid reservoir 300 is relatively high, H1≤20mm, and the height position of the bracket 200 can be close to the partition 340, ensuring that the partition 340 is located between the plane where the upper end surface of the bracket 200 is located and the plane where the lower end surface is located, so as to enhance the support of the bracket 200 for the second main shell 310, improve the natural frequency of the liquid reservoir 300, and reduce high-frequency noise.

[0049] Reference Figure 1As shown, it can be understood that, in the present embodiment, along the height direction of the first main shell 110, the middle of the partition 340 and the middle of the bracket 200 are at the same height position, that is, the radial center line of the partition 340 along the first main shell 110 coincides with the radial center line of the bracket 200 along the first main shell 110. At this time, the supporting force of the bracket 200 on the structures on the upper and lower sides of the partition 340 in the second main shell 310 is balanced, and the supporting effect of the bracket 200 on the liquid reservoir 300 and the connection strength between the bracket 200 and the liquid reservoir 300 are better, thereby further increasing the installation stability of the liquid reservoir 300.

[0050] Reference Figure 2 and Figure 3 As shown, it can be understood that the bracket 200 is an integrally formed part and is formed by punching and bending a plate material. The height direction of the bracket 200 is defined to be parallel to the height direction of the first main shell 110, and the thickness direction of the bracket 200 is parallel to the line connecting the center of the compressor housing 100 and the center of the liquid reservoir 300 in the cross section of the compressor. The cross section is a cross section perpendicular to the up and down directions, and the width direction of the bracket 200 is perpendicular to both the height direction and the thickness direction of the bracket 200. Specifically, the bracket 200 includes a connecting plate 210, two first connecting arms 220 and two second connecting arms 230. The connecting plate 210 includes a positioning portion 211, two bending portions 212 and two connecting portions 213. The positioning portion 211 can be a flat plate structure, an arc plate structure or a plate structure of other shapes. The positioning portion 211 has a center line arranged along the thickness direction of the bracket 200. The two bending portions 212 are respectively connected to the two ends of the positioning portion 211 along the width direction of the bracket 200 and relative to the center of the positioning portion 211. The positioning portion 211 and the two bending portions 212 are arranged line-symmetrically, and are located between the first main shell 110 and the second main shell 310 bracket 200. The bending portion 212 is bent relative to the positioning portion 211 in a direction toward the second main shell 310, and the two connecting portions 213 are respectively connected to the ends of the two bending portions 212 away from the positioning portion 211, and the connecting portions 213 are bent relative to the bending portions 212 in a direction away from the second main shell 310, and the two connecting portions 213 are symmetrically arranged relative to the center line of the positioning portion 211.

[0051] Reference Figure 2 and Figure 3As shown, it can be understood that the two first connecting arms 220 are respectively connected to one end of the two connecting parts 213 away from the positioning part 211, the first connecting arms 220 are bent relative to the connecting plate 210 in the direction toward the first main housing 110, and the first connecting arms 220 are biased toward the outside of the connecting plate 210 along the width direction of the bracket 200, and the two first connecting arms 220 are symmetrically arranged relative to the center line of the positioning part 211. When the bracket 200 is connected to the compressor housing 100, the two first connecting arms 220 abut against the outer peripheral wall of the first main housing 110 and are fixed to the first main housing 110 by welding. The bracket 200 and the first main housing 110 have two connection positions, and the connection is stable and reliable.

[0052] Reference Figures 2 to 5 As shown, it can be understood that the two second connecting arms 230 are respectively connected to one end of the two connecting parts 213 away from the positioning part 211, the second connecting arm 230 is extended relative to the connecting plate 210 in a direction away from the first connecting arm 220, and the second connecting arm 230 is biased to the outside of the connecting plate 210 along the width direction of the bracket 200, and the two second connecting arms 230 are symmetrically arranged relative to the center line of the positioning part 211. In other words, the second connecting arm 230 and the first connecting arm 220 are respectively located on both sides of the connecting plate 210 along the thickness direction of the bracket 200. Specifically, the connecting plate 210 is provided with a hollow part 214, the outline of the hollow part 214 is roughly rectangular, a part of the structure of the hollow part 214 is located at the bending part 212, and the other part of the structure is located at the connecting part 213, and the second connecting arm 230 is connected to a side edge of the hollow part 214 away from the positioning part 211. Therefore, when processing the bracket 200, the other three edges except the edge of one side away from the positioning portion 211 are punched out of the position corresponding to the hollow portion 214 on the plate, and the plate material at this position is bent outward to form the second connecting arm 230. After the second connecting arm 230 is bent, the hollow portion 214 is formed at the original position, which is convenient for processing, and the second connecting arm 230 is connected to the connecting plate 210 as a whole, which is easy to process and has good structural strength. It is easy to understand that along the height direction of the first main shell 110, the height of the second connecting arm 230 is less than the height of the hollow portion 214. The second connecting arm 230 obtained after the above bending is polished to improve the processing accuracy and avoid burrs. Of course, the height of the second connecting arm 230 can be equal to the height of the hollow portion 214, and there is no need to cut or polish the second connecting arm 230 obtained after the above bending, which is convenient for processing.

[0053] Reference Figure 2 and Figure 3As shown, it can be understood that when the bracket 200 is connected to the liquid reservoir 300, the connecting portion 213 and the second connecting arm 230 both abut against the outer peripheral wall of the second main housing 310, and the second connecting arm 230 and the second main housing 310 are fixed by welding, and the connecting portion 213 provides a positioning function for the second main housing 310. Therefore, there are two positioning positions and two connecting positions between the bracket 200 and the second main housing 310, which is conducive to ensuring the connection strength between the bracket 200 and the liquid reservoir 300 and the accuracy of the connection position.

[0054] Reference Figure 2 and Figure 3 As shown, it can be understood that, thanks to the connection between the connecting portion 213 and the positioning portion 211 through the bending portion 212, the positioning portion 211, the bending portion 212 and the connecting portion 213 are not in the same plane, which is conducive to increasing the ductility of the connecting portion 213. When the bracket 200 is installed to the second main shell 310, the two connecting portions 213 are easier to unfold in opposite directions, which is convenient for installation, thereby improving the fit between the bracket 200 and the second main shell 310, improving the connection stability, and improving the stability of the liquid reservoir 300.

[0055] Reference Figure 4 and Figure 5 As shown, it can be understood that, thanks to the hollow portion 214 provided on the connecting plate 210, the ductility of the connecting portion 213 and the overall ductility of the bracket 200 can be further increased, so that the first connecting arm 220 fits more closely to the first main shell 110, and the connecting portion 213 and the second connecting arm 230 fit more closely to the second main shell 310, thereby improving the connection firmness and enhancing the stability of the compressor.

[0056] Reference Figure 2 As shown, it can be understood that the angle between the two relative walls of the two connecting parts 213 is defined as a, and the angle between the two relative walls of the two bending parts 212 is defined as b. It is easy to understand that a>b, and b satisfies: 60°≤b≤80°. b limits the range of a to a certain extent, so that b≥60°, and the angle between the two connecting parts 213 is increased by increasing the angle between the two bending parts 212, so that the connecting part 213 can better fit the second main shell 310, which is convenient for installation and improves the connection strength between the bracket 200 and the liquid reservoir 300; b≤80° is conducive to ensuring the ductility of the connecting part 213, thereby improving the fit and making the overall structure of the bracket 200 more compact. Therefore, 60°≤b≤80°, for example, b is 60°, 65°, 70°, 75° or 80°, etc., which can make the bracket 200 and the liquid reservoir 300 more fit, improve the stability of the liquid reservoir 300, and make the overall structure compact.

[0057] Reference Figure 2 and Figure 3 As shown, it can be understood that the first connecting arm 220 includes a fixing portion 221 and a welding portion 222, the fixing portion 221 is connected to the connecting portion 213, the welding portion 222 is connected to one end of the fixing portion 221 away from the connecting portion 213, and the welding portion 222 is bent relative to the fixing portion 221 in a direction away from the first main housing 110, and the welding portion 222 abuts against the first main housing 110 and is welded and fixed to the first main housing 110. The angle between the two opposite walls of the two fixing portions 221 is defined as c, and it is easy to understand that c limits the angle between the two opposite walls of the two welding portions 222 to a certain extent, and c satisfies: 20°≤c≤40°. c≥20°, and the angle between the two fixing parts 221 is increased to increase the angle between the two welding parts 222, so that the welding part 222 can better fit the first main shell 110, thereby improving the connection strength between the bracket 200 and the compressor housing 100; thanks to the bending arrangement of the welding part 222 relative to the fixing part 221, the fixing part 221 is brought closer to the center line of the positioning part 211, making the overall structure of the bracket 200 more compact, and c≤40° to avoid the angle between the two fixing parts 221 being too large, thereby ensuring the compactness of the bracket 200. Therefore, 20°≤c≤40°, for example, c is 20°, 25°, 30°, 35° or 40°, etc., which can make the bracket 200 fit more closely with the compressor housing 100, improve the stability of the accumulator 300, and make the overall structure compact.

[0058] Reference Figure 2 and Figure 5 As shown, it can be understood that each first connecting arm 220 further includes a reinforcing rib 223, two reinforcing ribs 223 are respectively located on the back sides of the two first connecting arms 220, the reinforcing rib 223 is connected between the fixing portion 221 and the welding portion 222, and the reinforcing rib 223 extends from the upper end surface to the lower end surface of the first connecting arm 220. Specifically, the reinforcing rib 223 is a plurality of triangular structures connected in sequence from top to bottom, which is conducive to enhancing the overall structural strength of the first connecting arm 220 and the bracket 200, thereby improving the stability of the liquid reservoir 300 and the compressor as a whole, and reducing high-frequency noise.

[0059] Reference Figure 2 As shown, it can be understood that the two reinforcing ribs 223 are arranged symmetrically with respect to the center line of the positioning portion 211, and the angle between the two back-facing walls of the two reinforcing ribs 223 is defined as d, which satisfies: 65°≤d≤75°. When d≥65°, the size of the reinforcing ribs 223 can be large enough to ensure the structural strength of the bracket 200; when d≤75°, the material usage of the bracket 200 can be reduced, and the weight and cost can be reduced while meeting the structural strength requirements. Therefore, when 65°≤d≤75°, the structural strength of the bracket 200 can be increased, the stability of the compressor can be improved, the noise can be reduced, and the production cost can be reduced.

[0060] Reference Figure 2 As shown, it can be understood that, along the width direction of the bracket 200, the width of the positioning portion 211 is defined as W1, the width between the extended ends of the two second connecting arms 230 is W2, the width between the ends of the two welding portions 222 away from the fixing portion 221 is W3, and the width between the ends of the two welding portions 222 close to the fixing portion 221 is W4, which satisfies: 0.3≤W3 / (W4+W2-2*W1)≤0.8. It is easy to understand that W2 is the matching size of the bracket 200 and the second main shell 310, and W3 is the matching size of the bracket 200 and the first main shell 110. In this embodiment, the outer diameter of the first main shell 110 is greater than the outer diameter of the second main shell 310, so W3>W2. W1 and W4 are related to the compactness of the bracket 200. W3 / (W4+W2-2*W1) can be understood as defining the relationship between W2 and W3 according to the values ​​of W1 and W4, so that W3 / (W4+W2-2*W1)≥0.3, which can avoid the disadvantage that W3 is too small, making it difficult to install the bracket 200 to the first main shell 110, and avoid the disadvantage that W2 is too large, resulting in a small contact area between the bracket 200 and the second main shell 310 and vibration; make W3 / (W4+W2-2*W1)≤0.8, which can avoid the disadvantage that W3 is too large, resulting in a small contact area between the bracket 200 and the first main shell 110 and difficulty in welding, and can avoid the disadvantage that W2 is too small, resulting in difficulty in installing the liquid reservoir 300. Therefore, by making 0.3≤W3 / (W4+W2-2*W1)≤0.8, the connection stability between the compressor housing 100 and the accumulator 300 can be improved, thereby improving the stability of the compressor and reducing noise.

[0061] Reference Figure 4As shown, it can be understood that along the height direction of the first main housing 110, the height of the connecting plate 210 is defined as H2, and the height of the second connecting arm 230 is defined as H3, which satisfies: 0.6≤H3 / H2≤0.8. It is easy to understand that the value of H3-H2 can be understood as the sum of the heights of the structures located on the upper and lower sides of the hollow portion 214 in the connecting plate 210. Make H3 / H2≥0.6, so that H3 is larger, so as to increase the height of the bracket 200, increase the contact area between the bracket 200 and the compressor housing 100, and enhance the connection strength, and make H2 not large, so as to avoid the height of the structures located on the upper and lower sides of the hollow portion 214 in the connecting plate 210 being too small to affect the structural strength of the bracket 200; make H3 / H2≤0.8, so that H3 is not too large, so as to avoid cost increase, and make H2 larger, so as to increase the contact area between the bracket 200 and the second main housing 310. Therefore, setting 0.6≤H3 / H2≤0.8, for example, the value of H3 / H2 is 0.6, 0.7 or 0.8, etc., can increase the structural strength of the bracket 200, improve the connection strength between the bracket 200 and the compressor housing 100 and the liquid reservoir 300, improve stability, reduce noise, and reduce costs.

[0062] Reference Figure 4 As shown, it can be understood that in order to fill enough solder, the second connecting arm 230 is provided with two welding holes 231, and the two welding holes 231 are arranged at intervals along the height direction of the first main shell 110. The shape of the welding hole 231 can be circular, U-shaped, etc. The distance between the centers of the two welding holes 231 in the height direction of the first main shell 110 is H4, which satisfies: 0.2≤(H3-H4) / H2≤0.4. H3-H4 can be understood as the sum of the heights of the structures on the back sides of the two welding holes 231 in the second connecting arm 230. Through the above arrangement, the structural strength of the second connecting arm 230 can be guaranteed and the distance between the two welding holes 231 can be appropriate, thereby improving the connection strength between the second connecting arm 230 and the second main shell 310, improving the stability of the liquid reservoir 300, and reducing noise.

[0063] Reference Figure 1 As shown, it can be understood that along the height direction of the first main shell 110, the height of the second main shell 310 is defined as H5, and the distance between the lower end surface of the partition 340 and the upper end surface of the second main shell 310 is H6, satisfying: 0.5≤H6 / H5≤0.6, so that the height position of the partition 340 in the second main shell 310 is appropriate to ensure the supporting effect of the partition 340 on the air intake pipe 350 and the gas-liquid separation effect. At the same time, the height position of the partition 340 is adapted to the height position of the bracket 200 to improve the connection strength between the bracket 200 and the liquid reservoir 300, enhance the stability of the liquid reservoir 300, and reduce noise.
